Step 4. Voltage measurement at the B-110 
back-up lamp switch connector.

(1) Disconnect the connector, and measure at the 

wiring harness side.

(2) Ignition switch: ON

(3) Voltage between B-110 back-up lamp switch 

connector terminal No.2 and body earth

OK: System voltage

Q: Is the check result normal?

YES : 

Go to Step 5.

NO : 

Go to Step 6.
